Grandpa's Great Escape Live! is a brand-new family show based on the book of the same title by David Walliams. The show tells the story of Jack's Grandpa with dementia still believing that World War II hasn't ended and longing to re-live his past. When his family can no longer look after him he is moved to an old people’s home called Twilight Towers and things start getting nasty there. Jack and his Grandpa need to find a way to escape so they go on a new adventure, or should I say mission, and try to make a daring escape.
